I like this because it is steel. Hot stays hot, cold stays cold. I dont have any complaints yet. I know it will get marked up from food, but if you use your pans, they have marks too. It will only stay pristine if unused so what would be that point? We've done soups, smoothies, peanut butter and chopped cheese amd onions without trouble.  I plan on using a lot during the holidays. Broccoli cheese soup is next. My hubby loves this container. Highly recommend.
